Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If endoscopy is used to detect mucosal tissue health, then early diagnosis capability is improved, but image resolution remains poor and requires anesthesia or contrast agents
Solution Approach 1:
The patent replaces the mechanical imaging system of endoscopy with an optical spectroscopy system. Instead of using cameras and lenses to capture images, the system uses light sources and spectrometers to analyze the spectral characteristics of mucosal tissue, substituting mechanical imaging with optical field-based measurement.
Solution Approach 2:
The patent changes the measurement parameter from visual image information to spectral signal information. By measuring the absorption and reflection characteristics of light across different wavelengths, the system transforms the diagnostic basis from qualitative image interpretation to quantitative spectral analysis, improving both resolution and objectivity.
2Ease of operation
If conventional optical biopsy is used for real-time imaging, then tissue specimen collection is avoided, but diagnostic accuracy suffers due to subjective image interpretation
Solution Approach 1:
The patent replaces subjective visual interpretation with automated spectral analysis. The system uses computers to process spectral signals and objectively determine tissue health status, eliminating human subjectivity from the diagnostic process while maintaining real-time capability.
Solution Approach 2:
The patent introduces spectral signals as an intermediary between the tissue and the diagnostic conclusion. Instead of directly interpreting images, the system measures spectral characteristics that serve as objective intermediaries, providing a quantifiable basis for diagnosis that reduces subjective judgment.
3Difficulty of detecting and measuring
If endoscopy with contrast agents is used for diagnosis, then detection capability is improved, but patient safety deteriorates due to side effects from contrast agents
Solution Approach 1:
The patent replaces contrast agent-based enhancement with intrinsic optical property measurement. By analyzing the natural absorption and reflection characteristics of tissue at different wavelengths, the system achieves detection capability without introducing external substances that could cause harmful side effects.
